ReSpeaker 2-Mics Pi HAT is a dual-microphone expansion board for Raspberry Pi designed for AI and voice applications. This means that you can build a more powerful and flexible voice product that integrates Amazon Alexa Voice Service, Google Assistant, and so on.

The board is developed based on WM8960, a low power stereo codec. There are 2 microphones on both sides of the board for collecting sounds and it also provides 3 APA102 RGB LEDs, 1 User Button and 2 on-board Grove interfaces for expanding your applications. What is more, 3.5mm Audio Jack or JST 2.0 Speaker Out are both available for audio output.

Note:

This product does not include the Pi Zero board

Hi Shahrul, I tested it and it works. We suspect the driver issue. please print the arecord -l and aplay -l to verify the driver installation. We also can use the audacity to test the record and play functions by selecting seeed-2mic-voicecard as input and speaker. thanks. Bill

Hi there~ Sorry to tell you that all of the feature you mentioned is not supported by ReSpeaker 2-Mics Pi HAT. If you need those fuction,please see our mic array # https://www.seeedstudio.com/ReSpeaker-Mic-Array-Far-field-w%2F-7-PDM-Microphones--p-2719.html # Regards

Hi Bail, Please use the pixels.off() function to turn off the light and then reboot. It will not turn on the leds after rebooting. For more info about the pixels.off, please refer to https://github.com/respeaker/mic_hat.git thanks. Bill

Hi there~ The jst port only output single track audio, so seems there is no difference between
two speakers and one. Still, if you want to use two speakers you need to connect two speakers in series or you may damage both speakers. Both speakers may work,but the sound will be very small.

Thats not true ... i was ordering one 6/6/217 and the status is still in "not in delivery"
Is the new announced date 07/15/2017 for my order from June ?
This is not the first time for me delivery at not announced date , this happens now 3 times.
Best regards Joachim

Think I solved it: Problem for me seemed to be that pulseaudio was installed AFTER this driver. The /etc/pulse/default.pa file was the distribution standard which seems to work incorrectly. When using this one from the repository https://github.com/respeaker/seeed-voicecard/blob/master/default.pa there are no configuration profiles being displayed in pavucontrol but input and output channels work at the same time. This made me run google-assistant-demo correctly.

Haven&#39;t tried the solution yet. Hopefully it works.
I do find it surprising that there are six reviews, all with 5 stars saying &#39;Good Product!&#39; - are these shill reviews? Especially during the period that no one could come up with a solution.
Be forewarned...
